Magnetic fields on rectangular objects have many uses, including:
-
Calculating interaction forcesAnalytical expressions for the magnetic field of a rectangular conductor with current can be used to calculate the interaction force between a magnet probe and the conductor.
-
Understanding magnetic field distributionExpressions for the magnetic field distribution of rectangular permanent magnets can help understand the relationship between the magnetic field and the magnet’s size, and the distance from the magnet’s surface.
-
Studying heat transferExperiments have shown that a magnetic field can increase the heat transfer coefficient in a rectangular duct filled with a magnetic fluid.
-
Closed-form expressionsClosed-form expressions for the magnetic fields of rectangular current loops and solenoids can be used to avoid approximations in analytical models and reduce computation time in computer simulations.
A magnetic field is a physical field that describes how magnetic materials, electric currents, and moving electric charges are influenced by magnetism.
